SU LKY- PLOW CARRIAGE.

SPECIFICATION forming part of Letters Patent No. 229,375, dated June 29,1880. Application led April 2, 1880. (No model.)

To all whom it may concern:

Be it known that I, LE ROY GAHLLL, of Kalamazoo, in the StateofMichigan, have invented certain new and useful Improvements in Sulky-Plow Garriages; and I do hereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,making a part of this specification.

My invention relates to sulky-plowcarriages; and it consists in theconstruction and arrangement of devices for turning the axles to adjustthe wheels, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawings, in whichjFigure l is a vertical longitudinal section; Fig. 2, a face viewthereof, showing one mode of attaching lever; Fig. 3, a side elevationof the device attached to the axle, and Fig. 4 a front or face view. Y

In a sulky-plow carriage such as I propose more particularly to apply myinvention to there 1s under each end of the axle-tree a forked castingor a double hanger, or one or two downwardly projecting arms, throughwhich the short axle is passed. A represents this short axle, which isformed with an arm, B, extending at right angles to it, and at the endof this arm projects the spindle G to receive the driving-wheel. Inother words, the axle A is formed with a crank in the usual manner.

On the axle A is placed acasting composed of a socket or collar, D,circular disk D', and semi-tube or half-barrel D2, all in one piece.

The socket or collarD is slipped over the axleV A, the part D2 fittingaround the inside of the arm B, while the disk Dl projects in theopposite direction from the axle, as shown.

One arm of the hanger comes close up to the socket D, and a collar, Ii,is placed on the axle against the opposite side of the hangerarm andfastened by a set-screw, a, whereby the casting is held in place on thecrank of the axle. However, if deemed necessary, the half-.barrel of thecasting may be held or fastened to the crank by any suitable orconvenient means.

On the face of the disk Dl are made two or more grooves, b, runningdiametrically, for the adjustment of a lever, Gr, which is fastened by abolt, IL, and nut t', and by which the axle may be turned so as to bringthe crank-arm at any angle desired to raise and lower the wheel. Theobject of adjusting the lever G on the face ofthe disk is to accommodatethe lever to the position of the rack-bar, in which the lever is to beheld in the dierent positions,

By means of the grooves b in the disk there can, however, be but alimited number of adjustments of the lever, and for this reason in somecases I provide the disk D on its face with a series of radialcorrugations, m, and place upon the bolt 7L acorresponding'ly-corrugatedwasher, I, and in the outer side of this washer is a single diametricalgroove or recess to receive the lever Gr, which is then fastened inplace by the nut t'. In this case there will then be as many adjustmentsas there are teeth or corrugations on the parts Dl and I.

If desired, the castings D D D2 may be permanently fastened to the axle,and the part D' may be of any desired form, round, oval, square, orother shape.

The device D Dl D2, herein termed casting, may be made in any othersuitable manner besides casting.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

l. In a sulky-plow carriage, the device herein described, consisting ofthe socket or collar D, disk D', and semi-tube D2, and provided withmeans for adjusting the lever thereon.

2. The combination, with a crank-axle, of the device D D D2, having thepart D' corrugated, as described, the corrugated Washer I, lever G, andbolt and. nut, substantially as herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this2d day of April, 1880.-

LE ROY cAEILL.
